Title: Nuclear magnetic resonance apparatus
Inventor: KAWAGUCHI HIROMI
IPC: A61B5/055
Filed: 1988-07-20
Abstract: PURPOSE:To prevent an erroneous diagnosis in medical treatment by suppressing the artifact due to the cyclical body motion of an examinee by a method wherein a computer inputs the output signal of an impedance change detector to control the transmission point of time of the high frequency pulse due to a high frequency transmitter-receiver in synchronous relation to the cyclical change of impedance. CONSTITUTION:When a high frequency current is allowed to flow to a high frequency coil 11 through an impedance bridge 13 and a matching circuit 12 by utilizing the function of a high frequency transmitter-receiver 14 as a high frequency power supply, the output signal of the impedance bridge 13 is zero in an equilibrium state and, at a time shifted from the equilibrium state, the high frequency signal proportional to the shift quantity is outputted. An impedance change detector 15 amplifies the change quantity of said signal to apply A/D conversion thereto and inputs the converted digital value to a computer 16. The computer 16 receives said digital value to calculate the cycle of the body motion of an examinee and further calculates the point of time becoming a state of the same slice surface on the basis of said cycle to control the transmission point of time of the high frequency pulse of the corresponding high frequency transmitter-receiver 14. By this method, the artifact generated by respiration can be reduced to a large extent.

Abstract: PURPOSE:To obtain a sufficient common mode input range and to improve the differential gain, by constituting so that the common mode component of a potential change applied to an input terminal is cancelled and the differential component only is amplified. CONSTITUTION:Input terminals 45, 46 are connected to an amplifying circuit 44 and the output is given to a gate of an MOSFET41. Then, the differential component out of signals applied to the input terminals 45 and 46 does not give any effect on the output of the circuit 44, is sufficiently amplified at MOSFETs41, 42 and a load element 43 and appears at an output terminal 47. The common mode component out of the signals applied to the input terminals 45, 46 is amplified at the circuit 44 and applied to the gate of the MOSFET41. The potential change at the output terminal 47 resulted from this becomes opposite in polarity to the potential change at the output terminal 47 due to the potential change of gate of the MOSFET42. Thus, the common mode component can be cancelled by adjusting the gain of the amplifying circuit 44.

IPC: B24B53/00
Filed: 1987-07-23
Abstract: PURPOSE:To always perform both tooling and dressing by constituting a device in such a way that a grinding stone for dressing is bonded onto the surface including sections to be ground of a work, and performing grinding accompanied with the cutting of said grinding stone. CONSTITUTION:A grinding stone for dressing 3 is bonded onto a work 1. Grinding for hard and brittle materials such as rock crystals, glass and the like is performed by a blade 2 accompanied with cutting of the grinding stone for dressing 3 at all time. Accordingly, the blade 2 is subjected to the act of both tooling and dressing by the grinding stone for dressing 3 while the work is being processed, it may thereby perform the processing on the work 2 with optimum grinding performance kept at all time. When the grinding stone for dressing 3 is bonded onto the surface including sections to be ground of the work 1 (bonded surface 5), the sections to be processed of the work 1 is also firmly fixed on the grinding stone for dressing as well. This constitution thereby prevents internal stresses from being incurred into the work 1 more than necessary, and also prevents the sections to be processed from being cracked because of internal stress.
